摘要：
An encoder is capable of being used to compensate for the tilting of a movable object in an apparatus. The encoder includes a fixed scale, and a movable scale integrated with an object that moves during an operation of the apparatus and having a plurality of patterns that are out of phase from each other with respect to the direction of movement of the object. The encoder may be employed by a hard disk drive (HDD) and a servo track recording apparatus. The movable scale is integrated with an actuator arm of the HDD for positioning a read/write head of the HDD, and the fixed scale is fixed to the housing of the HDD. The servo track recording apparatus can use the encoder to record servo track information precisely on a disk.
摘要（中）：
编码器能够用于补偿装置中可移动物体的倾斜。 所述编码器包括固定刻度，以及与所述物体集成的可移动刻度，所述可移动刻度在所述装置的操作期间移动，并且具有相对于所述物体的移动方向彼此异相的多个图案。 编码器可以由硬盘驱动器（HDD）和伺服记录记录装置使用。 移动刻度盘与HDD的执行器臂集成，用于定位HDD的读/写头，固定刻度尺固定在HDD的外壳上。 伺服记录装置可以使用编码器将伺服轨道信息精确地记录在盘上。
